Carchi Andes Toad
The Carchi Andes toad (''Rhaebo colomai'') is a species of toad endemic to the western slopes of the Andes in northern Ecuador and southern Colombia. It is listed as an endangered species due to a restricted range and habitat loss. Description ''Rhaebo colomai'' are medium-sized toads: males measure and females in snout–vent length. Habitat and conservation This species is known only from three locations: the type locality ("Cabacera del Rio Baboso, cerca a Lita', Carchi Province, Ecuador"), one other locality close by in the province of Carchi, in the northwestern Andes of Ecuador, and one locality on the Colombian Massif The Colombian Massif (from the Spanish Macizo Colombiano), also known colloquially as ''Nudo de Almaguer'', refers to a group of mountains within the Andes of south central Colombia. The massif is mainly within the area of the Cauca, Huila, and ... in the Nariño Department. It has been recorded from 1,180 to 1,500 m asl. The holotype was co ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontificia Universidad Católica Del Ecuador
The Pontificia Universidad Católica del Ecuador (PUCE) (English: ''Pontifical Catholic University of Ecuador'') is a Pontifical Catholic university founded in 1946 in Quito, Ecuador. History The university opened in the fall of 1946, with Carlos María de la Torre, archbishop of Quito, officiating. Aurelio Espinosa Pólit of the Society of Jesus (Jesuits) was the first rector. That fall there were 54 students and jurisprudence was the single faculty. Pope Francis visited the campus of PUCE on his trip to South America in July 2015. Location The principal campus of the university is in Quito. Other campuses are in Ambato (established in 1982), Esmeraldas (1981), Ibarra (1976), Santo Domingo de los Colorados (1996), and a regional campus in the province of Manabí (1993). The campus in Cuenca later became the Universidad del Azuay. All branches follow the National System PUCE.

Amphibians Of The Andes
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a drama ...

Rhaebo
''Rhaebo'' is a genus of true toads, family Bufonidae, from Central and South America. They are distributed from Honduras to northern South America including the Amazonian lowlands. Common name Cope toads has been suggested for them. Taxonomy The genus was removed from the synonymy of ''Bufo'' in 2006; an alternative view has been to treat it as a subgenus of ''Bufo''. At present, it is widely recognized as a genus. ''Andinophryne'', consisting of three species, was recognized as a separate genus until 2015 when it was found out that its recognition rendered ''Rhaebo'' paraphyletic. An alternative to synonymizing it with ''Rhaebo'' would have been to erect a new genus for '' Rhaebo nasicus'', but this would have caused difficulty in assigning species without molecular data to correct genus. Description ''Rhaebo'' are characterized as lacking cephalic crests, having omosternum, distinctively wide sphenethmoid, prominent and notched exoccipital condyles, and yellowish-orange sk ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Trunk (botany)
In botany, the trunk (or bole) is the plant stem, stem and main wooden axis of a tree, which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production. Occurrence Trunks occur both in "true" woody plants and non-woody plants such as palm (plant), palms and other Monocotyledon, monocots, though the internal physiology is different in each case. In all plants, trunks thicken over time due to the formation of secondary growth (or in monocots, pseudo-secondary growth). Trunks can be vulnerable to damage, including sunburn. Vocabulary Trunks which are cut down for making lumber are generally called logs; if they are cut to a specific length, called bolts. The term "log" is informally used in English language, English to describe any felled trunk not rooted in the ground, whose roots are detached. A tree stump, stump is the pa ...

Zoologische Mededelingen
''Zoologische Mededelingen'' was a peer-reviewed open access scientific journal publishing papers and monographs on animal systematics. The publisher was the National Museum of Natural History Naturalis in the Netherlands. The first issue appeared in 1915, as the official journal of Naturalis' predecessor, the Rijks Museum van Natuurlijke Historie. Earlier, the museum published ''Muséum d'Histoire Naturelle des Pays-Bas'' (volumes I-XIV, 1862-1908) and ''Notes from the Leyden Museum'' (volumes I-XXXVI, 1879-1914), which mainly covered the fauna of the Netherlands and the former Dutch colonies. ''Zoologische Mededelingen'' was indexed in ''The Zoological Record'' and ''BIOSIS''. A complete backlist of published volumes is presented on the institutional repository of Naturalis. The last article was published in 2014 and the journal was merged into the ''European Journal of Taxonomy The ''European Journal of Taxonomy'' is a peer-reviewed open access scientific journal for descrip ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture (folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae (helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae (European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae (American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps on the skin ...
